    Does anyone know whether 1932 eight cylinder distributor caps are the same as those for 1930 and also whether there is a quality difference between the original (Delco? Stromberg?) caps and replacement Echlin caps? Can one even visually distinguish between the caps from different manufacturers? Thanks.


    Hi Joe,

    Though they look similar, the 1930 8 cylinder distributor caps are different than the 1932 8 cylinder distributor caps. The 1930 A and B cap is the Delco part 828682. Just to make it interesting, the 1930 Model C used a different distributor, and therefore, a different cap, Delco # 823525, which is slightly smaller in physical size. The 1932 Model 54 used the same distributor as the 1931 Model 43, and happily use a common cap, Delco # 1844659. So as you can see, they are all different part numbers in this era of cars, even though physically, they kind of all have a family resemblance, being 2 piece caps with a cap cover that retains the 9 ignition wires in place. The good news is that at least Pierce kept using the #1844659 cap on the 1933-38 8 cylinder engines, also on Studebaker 8’s and Auburn 8’s….not that it makes them plentiful or anything, but maybe a little less rare!

    Part number is the best way to distinguish them, although some of the manufacturer’s molded in a maker’s mark. In addition to Delco-Remy caps, I’ve seen Standard, Echlin, Mapco, P&D, as there were several aftermarket brands that made these. Some of them had no familiar Delco-Remy mark, nor any marking at all. I have not noticed much difference between the various brands from a quality perspective, perhaps another member has a story about a particular brand that tended to carbon track inside, or one that was more brittle than another.

    Happy motoring,

    Chris Diekman
